100uF Motor Run Caps - Page 2

jacco vermeulen · 4th November 2009, 11:02 PM

very small for MKP, even Chinese manufactured CBB60 or CBB61 are larger.

The 400uF/450V caps on offer by that seller are stated to be 50x110mm.
An Epcos MKP pulse cap of that size has 2.5 times the height and almost twice the diameter.

Good point Jacco.

Come to think of it, they look the same as those sold in a local hardware store as electrolytic "motor start" caps.

Hey, it's cheap enough... someone should snag one and cut it open

Cheers!

You can also shop electric motor repair shops. I picked up a start cap for my dust collector for 6 bucks. They had about 1000 different values, voltages, and manufactures.

Large motor runs are all somewhat inductive, but then so are most electrolytics.
These are probably ok, and at the price it is hard to imagine you could go wrong.

Odd that the seller who is based in Hong Kong listed them on eBay Italia.. Io penso di comprare qualche pezzi di questo condensatore.

Run the auction number through ebay.com or ebay.ca or ebay.co.uk, Kevin, it's just a worldwide auction I think...

Cheers!

Don't forget motor run caps are ac.

Why would you use one of these opposed to a standard 100uf film cap?

huh? A polipropilene cap is a poliprpilene cap anyway

why to use these instead an electrolitic? Give a try, remove your electrolitics from your tube amp and give a chance to these motor run poli caps and hear your music as usually...
